[pve-devel] [PATCH v2 ha-manager 1/2] tests: simulate stale maintainance node caused by simultaneous cluster shutdown

In the test log, it can be seen that the service will unexpectedly be
migrated back. This is caused by the service's maintainance node
property being set by the initial shutdown, but never cleared, because
that currently happens only when the service is started on a different
node. The next commit will address the issue.

Changes in v2:
* Rebase on current master.
* Split out introducing the test into a dedicated patch.
